Question

FIND THE VALUE OF X IF [-2/3]-3/8 (-2/5)X+(-2/5)3X+2

Answer 1

Answer:

This system of equation is of the form

a

1

x+b

1

y+c

1

=0

a

2

x+b

2

y+c

2

=0

where a

1

=2m−1,b

1

=3,c

1

=−5

and a

2

=3,b

2

=n−1 and c

2

=−2

For infinitely many solutions, we must have

The given system of equations will have infinite number of solutions, if

3

2m−1

=

n−1

3

=

−2

−5

⇒

3

2m−1

=

n−1

3

=

5

⇒

3

2m−1

=

2

5

and

n−1

3

=

2

5

⇒4m−2=15 and 6=5n−5

⇒4m=17 and 5n=11

⇒m=

4

17

and n=

5

11

Hence, the given system of equations will have infinite number of solutions, if m=

4

17

and n=

5

11
